NEM for instance has 3000 stakeholders. Taint analysis was used to remove hundreds of sockpuppets and the large scale diminishes any return from sockpuppets.
That I find hard to believe, communitycoin tried to distribute to just 1000 geniune and found that hard to do and reduced it the 500 and checks showed that only like 300 odd where proper users etc so I fond 3000 individuals in these parts hard to believe.
NxT had 20,000+ addresses when NEM was announced NEM was new code based on a proven (but distribution flawed) concept. Probably a good half or more of thread 1 for NEM were NxT holders like me?
Communitycoin on the other hand has no prior base to attract, has an unappealing unprofessional name and a complicated IPO for what could be worthless coins.
Sockpuppets are more common for obscure coins.
Communitycoin seems to be the fairest distribution so far, and will prove to be far from 'worthless' as you put it. As per OP 100% premine is fine as long as there's an honest and fair distribution.
